Quadriphase shift keying
WebAcronym Definition; QSK: Full Break-In (radiotelegraphy): QSK: Quick Start Kit: QSK: Proceed with Transmission (Ham radio): QSK: Quadriphase Shift Keying Quadrature phase shift keying (QPSK) is another modulation technique, and its a particularly interesting one because it actually transmits two bits per symbol. In other words, a QPSK symbol doesnt represent 0 or 1it represents 00, 01, 10, or 11. This two-bits-per-symbol performance is possible because the carrier … See more When used for analog signals, frequency modulation and amplitude modulation lead to continuous variations in the frequency or amplitude of a carrier wave. … See more Examples of common digital modulation types are OOK (on/off keying), ASK (amplitude shift keying), and FSK (frequency shift keying). These schemes cause the … See more Compared to modulation schemes that transmit one bit per symbol, QPSK is advantageous in terms of bandwidth efficiency. For example, imagine an analog … See more
